Puzzle & Dragons developer GungHo Online expects to rake in around $1.2 billion in revenue this year, and because it keeps its overhead low, it expects to keep about $700 million of that figure after expenses. These numbers are from CEO Kazuki Morishita, who recently spoke with CNN Fortune about the company's runaway hit game and business in general.

He attributes at least some of his company's success to his experience as a Manzai artist and stand-up comedian - believe it or not.

"I genuinely enjoy entertaining people - I get a thrill out of it," Morishita said. "Game companies should entertain their fans and users. It can never just be about the business-to-business aspects of the industry."

Morishita also said that GungHo has 10 or so games in development, though he would not disclose any more details. The studio's last game was Puzzle & Dragons Z on the 3DS, its first boxed retail release. The game proved to be a hit in Japan, selling more than 1.2 million units in its first month.

GungHo sold a controlling interest in the company last year to investment firm SoftBank last year. The company owns a controlling stake of more than 58 percent. SoftBank is a major player in the space because it also holds 51 percent of Clash of Clans developer Supercell.
